+# Cleanup Commands for Stuck Celery Tasks
+
+## Quick Commands
+
+### 1. Restart Celery Worker (to apply code changes)
+```bash
+docker restart mix_celery_worker
+docker logs -f --tail 50 mix_celery_worker
+```
+
+### 2. Run Cleanup Script (Interactive)
+```bash
+# Copy script to container
+docker cp cleanup_stuck_photos.py mix_web:/app/
+
+# Run interactively
+docker exec -it mix_web python manage.py shell
+>>> exec(open('cleanup_stuck_photos.py').read())
+```
+
+### 3. Manual Cleanup (Django Shell)
+```bash
+docker exec -it mix_web python manage.py shell
+```
+
+Then run:
+```python
+from django.db import connection
+from products.models import ProductPhoto, PhotoProcessingStatus
+from django.core.files.storage import default_storage
+
+# Activate schema
+connection.set_schema('mixflowers')
+
+# Find photo #6
+photo = ProductPhoto.objects.get(id=6)
+print(f"Photo: {photo}")
+print(f"File path: {photo.image.name}")
+print(f"File exists: {default_storage.exists(photo.image.name)}")
+
+# Option 1: Delete the record
+photo.delete()
+
+# Option 2: Clear the image field (keep record)
+# photo.image = None
+# photo.save()
+
+# Clean up stuck processing statuses
+stuck = PhotoProcessingStatus.objects.filter(status__in=['pending', 'processing'])
+print(f"Found {stuck.count()} stuck statuses")
+stuck.update(status='failed', error_message='File was deleted before processing')
+```
+
+## What Was Fixed
+
+1. **FileNotFoundError handling**: Task now fails immediately instead of retrying when file is missing
+2. **File existence check**: Added check before processing to catch missing files early
+3. **Status updates**: PhotoProcessingStatus is properly updated to 'failed' when file not found
+
+## Testing
+
+After restarting Celery worker:
+1. Upload a new photo - should process normally
+2. Check logs - should not see retry loops for missing files
+3. Verify stuck tasks are cleaned up
